Binary format Trajectory format (binary) BinPos Scripps Research Institute BinPos format is a binary formatted file to store atom coordinates. It is basically a translation of the ASCII atom coordinate format to binary code. The only additional information stored is a magic number that identifies the BinPos format and the number of atoms per snapshot. The remainder is the chain of coordinates binary encoded. A drawback of this format is its architecture dependency. Integers and floats codification depends on the architecture, thus it needs to be converted if working in different platforms (little endian, big endian). Scripps Research Institute BinPos 1.22
